Baltimore County police said the grandson of two elderly people who were found slain in their home earlier this week has been found in Oklahoma, and they're now considering him a suspect in the killings.

Matthew Long, 31, is in fair condition after being brought to an Oklahoma hospital on Sept. 11 after overdosing on an undisclosed drug at a Weatherford, Okla., hotel room, according to hospital officials.

An Oklahoma City police affidavit said a search warrant was executed to obtain fingernail and blood samples from Long.

Baltimore police issued an arrest warrant for him after his grandparents, 87-year-old Vaughn Pepper and 85-year-old Marjorie Pepper, were found dead Sept. 10 in their home in Pikesville. Police said the victims suffered from blunt force trauma.

Police said Long left a note at the Oklahoma hotel saying he was sorry for what he did.

Hillary Clinton did not have a State Department email account while she served as America's top diplomat, a senior state department official said Monday, and instead used a personal email account during her four years on the job.
